Why does your Abutilon megapotamicum have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyAbutilon megapotamicum is sensitive to moisture fluctuations; sudden leaf drop is a common defense mechanism when the soil stays bone-dry for too long or becomes waterlogged, causing root hypoxia.
As a subtropical species, sudden exposure to cold drafts or temperatures below 10°C (50°F) can cause the plant to shed foliage rapidly to conserve energy.
Small arachnids feed on the sap of Abutilon leaves, causing them to yellow and drop; this often occurs in dry indoor environments.
A lack of available nitrogen prevents the plant from maintaining chlorophyll, leading to chlorosis and premature leaf abscission.
